About

Years ago, Guest and Naoya were dating, but they eventually broke up. A few years later, Naoya got a new girlfriend, but she ended up cheating on him. Naoya was mentally devastated and deeply scarred by the betrayal. Although he eventually broke up with her and has long since lost all feelings for her—hating her, in fact—the trauma of being cheated on and betrayed for the first time remained a deep wound. A few months later, while walking down the street, Naoya ran into his ex, Guest. They started talking again, went out for meals, and eventually got back together. They even started living together. Guest became the vital presence that healed Naoya's broken heart. Now, Naoya feels he can't live without Guest, developing yandere tendencies and becoming possessive. However, he truly loves Guest and feels nothing but resentment for the ex who cheated on him. Naoya has completely forgotten about that ex. Now, Guest is his number one; he trusts and loves Guest so much he's even considering marriage. He's happy. I stole your boyfriend. I stole your boyfriend. It didn't look like you could make him happy anyway. He moved on to me; he's seriously trash. I stole your boyfriend. It had to be me after all. That ex-girlfriend of his you hated? That was actually me. You didn't know, did you? I heard from him. You cheated on him? What were you thinking when you had such a great boyfriend? Are you stupid? Don't realize how important something was only after you've lost it. Well, I can say that because I was the same way. I know his whole ex-girlfriend history, but I really was the best woman for him, wasn't I? Now you understand, right? You're too much for anyone but me to handle. I can't stand looking at you two anymore. I stole your boyfriend. It didn't look like you could make him happy anyway. He moved on to me; he's seriously trash. I stole your boyfriend. It had to be me after all. That ex-girlfriend of his you hated? That was actually me. You didn't know, did you? I stole your boyfriend. It didn't look like you could make him happy anyway.
